wA'rEn-chosn'r VALVE.

- one embodiment of my invention selected by me for the purpose ofillustrating the same, and a slight modification thereof, and saidinvention is fully disclosed in the fol lowing description and claims.

My present invention relates particularly to that class of flushingapparatus whichis used most largely where the water supply iscomparatively small so that the water supply pipe with which theapparatus is connected does not furnish the water in sufficient quantityto enable it to be used directly from the supply pipe for flushingpurposes, and in this class of devices it is customary to employ aflushing tank which is supplied with water fromthe water supply pipe, ormain and when the flushing action takes place, the flushing isaccomplished by means of the water discharged from'said tank.

My invention provides for controlling and operating the valve mechanismof the ap paratus 1 means of the pivoted closet seat and includes amongits novel features,means whereby a very light spring may be employed fornormally holding the water inlet valve upon its seat, thus permittingthe valve to be raised by a comparatively small amount'ot force exertedupon the valve stem in opposition to said spring, thus relieving thespud which connects the valve mechamsm with the porcelain bowl, or otherconnecting means from transverse stress, which tends to injure the sameor break the porcelain away where a very heavy spring is employed.

My invention also contemplates a novel valve construction forsubstantiallybalancing the water pressure and facilitating the movementof the valve in either direction and more specifically and in itspreferred form,

' Application filed October 30, 1913. Serial No. 798,299.

my invention also contemplates the provision cf connections independentof the main flushing connection for supplying water to the jet and alsopreferably to the rim of the bowl while the seat is in its lowest 0position so as to moisten the walls of thebowl, break the water seal ofthe bowl, and discharge an injector like stream from the jet through theempty trapand soil pipe so as to create a strong suction therethrough,

which will efiectually withdraw air continu'- ously from the bowl andthoroughly ventilate the same during the use of the apparatus and whilethe seat is depressed. The importance of this ventilating feature canhardly be over-estimated. By its use. an ap paratus of this charactercan be installed in lavatories, in hospitals, and other places withoutthe slightest possibility of contaminating the atmosphere of the room inwhich .75

it is installed so that the closet becomes as innocuous as any ordinarypiece of furniture. It may thus be installed, for example, in thebedroom of a hospital or of an invalid in a private house or in manyother locations ,80

where the ordinary toilet apparatus would be extremely objectionable andunsanitary, without any inconvenience and without impairing the purityof the atmosphere of the room. i

In a former application for Letters Pat ent of the United States filedby me on or about July 19, 1912, I have disclosed the broad idea ofventilating structure in connection with a specificform of valve mecha;

nism, especially adapted for use where prac tically unlimited volume ofwater supply is available, such as in large ofiice buildings and otherbuildings where a suflicient supply of water to effect the flushingwithout 96 the use of an intermediate tank can be had: J and my presentinvention is particularly designed to extend the advantages of thisinvention to that type of apparatus intended for use where acomparatively small supply of water is obtainable and the intervention Jof a supply tank is necessary.

It will also be understood that this apparatus can be utilized forpositively ventilating the room in which it is installed, for it theinlet valve is open, as by depressing the closet seat by means of thehand or otherwise without any use of the closet, the water seal will bebroken, as before described, the

suction j t will be discharged through the emptying trap and" willoperate continuously so long as the valve is held open, thus positivelywithdrawing large volumes'of air from the room and discharging themthrough the soil pipe. The operation of the device may be continued fora suflicient -period to thoroughly ventilate the-room, such as ahospital room or the room-of an invalidin a private home, or any otherroom or apartment in which the apparatus ;is installed. Obviously theair withdrawn from v the room bythe suction gof the ventilating jet willnecessarily be replaced by fresh air entering ,.t-hrough the doors,windows, or otherwise from outside the room. It will thus bese en thatthis [ventilating feature of 'my invention not only prevents the contamination; of the airby the use of the ap aratus ng apparatus for changingthe atmosphere in the ordinarpmanner, but may e em-- .ployedindependently as an active ventilatof the room, if desired.

' k '1' Referring to. 'the' accompanying drawing,

, Figure ,1 represents 'a sectional view of a i 25.

closet. bow-l providedwith my improved flushing and ventilatingapparatus. Fig. 2

. inbefore referred to is omitte Fig. 3 is a view raised or openposition. Fig. 4 represents .51 sectional view through the valve andcasmg on the line 4l of Fig.2 looking in the I direction of the arrows.

Fig. 5 is a sec-' tional view of a modified form of valve and casing inwhich the ventilatin feature heremounted in the cylindrical portion 14so as but the other advantageous features of the construction areretained. I

Referring to the drawings, 1 represents the bowl provided with the bowlrim flush passage 2, trap 3, and discharge 4: connecting with the soilpipe. I

5 indicates an aperture provided in the bowl structure for the insertionof a jet pipe at the lower end of the trap portion communicating withthe bowl proper and the bowl is also provided with an inlet aperture 6connecting with the rim aperture 2 to receive the spud or main flushpipe connection, a second spud receiving vaperture 7 connecting with therim aperture 2, and an inlet aperture 8 at the'lowe'r part of the bowlfor receiving the spud through which the jet pipe connection is made.

10 represents. the valve casing which is open at the top and bottomand'iis provided on opposite sides with apertures substantially in linewith each other. The bottom aperture is preferably the inlet aperture,although it is obvious that the valve mechacould be turned upside downwithout departing from the spirit of my invention. The bottom portion ofthe valve casing is.

in this instance exteriorly screw threaded to receive a clamping nut 11provided at its ed to connect it with the water inlet pipe and the upperend of said collar is rovided with a reduced aperture 12-and wit anannularvalve, the seat 13 surrounding said reducedapertu.re,.-. .Theinterior of the valve chamber'is provided,with a cylindrical portion 14:which forms a guide for the cylindrical valve. body hereinafter referredto, the said cylindrical portion being provided with an aperture.15.0Qmmunicating with the aperture 16 on oneside-of the valve casingwhich is! connected withthe main flushing aperture ,6 as he reinafterdescribed. The aperture 16 is shown in this instance as internally screwthreaded. The valve casing 10 is provided as before stated with anaperture on the oppositeside of the' casing,

' here indicated at 17, which is also shown internally threaded, and thecylindrical portion 14 extends upward into that portion of the valvebody opposite the lower portions of the apertures 15 and 16. A web 18extends from the upper part of the valve body to the upper part of thecylindrical guiding a portion across the upper portion of theaperture'.16 so that the communication between the aperture 17 and theaperture 16, through the valve casing, must be through the upper part ofsaid cylindrical guiding portion and through the lateral aperture 15;therein, as clearly'shownin Fig. 2. F j

A hollow cylindrical valve ,body 20, is

to be capable of sliding easily, vertically therein, said bodybein'g'olo'sed at its lower end and provided with a valve 21 on its,

lower face, the said valve being preferably composed of rubber, fibererother suitable material held in a recess formed in the bottom portionof reduced diameter with which the bottom of the valve body ispreferably provided, said valve coacting with the valve seat 13 beforereferred to so as .to open and close the water inlet aperture 12, Aportion I of the valve casing indicated at 22 below the cylindricalguiding portion 14 is of slightly larger diameter than the valve body asshown and the valve body is provided near the lower end of its hollowcylindrical portion with apertures 23 in its walls, the combinedareasof'said apertures beingpreferably somewhat less than the area ofthe aperture 12 in the preferred form of my invention, so that a portiononly of the water admitted'through the aperture 12 will pass throughsaid apertures 23 into the interior of the valve body and upwardtherethrough, when the valve is'in raised position as hereinafterdescribed. The valve body is provided With a vertically disposed stem 30M ran? top aperture therein, the said aperture be- 27 represents a coilspring which preferably surrounds the valve stem, the lower end engagingthe bottom of the interior of the cylindrical valve body, and the upperend engaging the washer 26, thus compressing the spring and alsocompressing the packing 25 between the washer 26 and the upper end ofthe recess in the plug or cap 24.

The diameter of the water inlet aperture 12 being small, a comparativelylight spring can be used tohold the valve 21 seated on the valve seat 13against the initial pressure of the water. It will also be noted thatthe interior diameter of the hollow valve body 20 is considerablygreater than the diameter of said inlet aperture 12 so that when thevalve body is in open position the water will exert some downwardpressure on .the interior bottom face of the valve body thus tending tobalance the valve and facilitating the closing movement of the sameagainstthe water pressure.

The upper end of the valve stem 30 is preferably screw threaded andprovided with an adjustable nut or equivalent device which engages aslot or recessed portion in a lever 31- secured to the hinged seat 32 insuch a manner that when the valve is in its closed position the seatwill be slightly raised from the top of the bowl at its forward edge, asshown in Fig. 1 so that the depression of the seat will compress thelight spring 27 and raise the valve, thus opening thewater supply inlet12, the valve and the seat 32 being both restored to normal position bythe spring 27. The lower part of the valve casing is preferably providedwith a hollow extension 35 having therein a passage 36 communicatingwith th enlarged portion 22 of the valve casing surrounding thecylindrical valve body 20 and the extension 35 is preferably providedwith two outlet apertures 37 and 38. The outlet aperture 38 is aconnected by means of a pipe 39 which extends through a spud and.stufling box of the usual construction indicated at 40, in the inletaperture 8 of the bowl, the said pipe 39 being extended (preferably, butnot necessarily) continuously, so that thedischarge end of the pipe 39extends through the jet receiving aperture 5 of the bowl, the dischargeend of thepipe or jet being indicated at 41 and being arranged todischarge longitudinally of the adjacent portion of the trap 3 below thelevel of the liquid seal. The aperture 37 in the extension 35 of thevalve casing is preferably connected by means or a preferably internallyrecessed on ace and provided with packing pipe 42 with a suitable spudor connection 43 so that it discharges through the aperture '7' whichmaybe located at one side of the aperture 6 andwhich communicates withthe rim flush passage2.

The valve casing is connected by means of a spud 45 screw collar 46 andnipple e7 with the main flushing aperture 16 of the valve casing, so asto both connect the valve casing to the rim flush passage 2 and supportthe valve casing with respect to the bowl. The aperture 17 f the valvecasing is connected by a pipe 50 with a tank 5-1, ordinarily a abledistance above the level of the valve to give the required head orpressure to the water to efl'ect a thorough flushing of the bowl afteruse in the manner hereinafter described, said tank being of suitablesize for this purpose.

- I will now describe the operation of my be in a normal position withthe seat slightly raised and the valve closed, as shown in Figs. 1 and2. -When the seat is occupied the forward edge will be depressed therebyraising the lever 31 and lifting the valve stem and valve against thepressure of the spring. \Vater supplied by the water inlet pipe willpass upwardly through the inlet aperture 12 around the cylindrical bodyof the valve and a portion only of the water will pass through theaperture or apertures 23 in the cylindrical valve body and thenceupwardly through the valve body to the upper part of the valve casing.The valve body when in its lowest position is below the flushingaperture 15 but when the valve is raised-the cylindrical body thereofcloses said aperture as shown in Fig. 3. The incoming water which passesup through the through the aperture 17 to the pipe 50 and thence to thetank 51 in which it accumulates during the time that the seat isoccupied. The remaining portion of the water admitted through the inletaperture 12 passes through the passage 86 in the extenpasses through thepipe 42 to the rim flush discharging a quantity of water therethroughwhich wets the interior surfaces of the Walls of the bowl above theliquid level of the. water seal, which are normally dry. and thus tendsto prevent the adhesion of is also discharged downwardly through thepipe 39 to the jet from which it is discharged through a.reducedaperture with great force. The action of this jet is twofold. First, itstarts the siphonic action of the trap and discharges the water in thetrap portion of the bowl, thus breaking the liquid sealand establishinga free connection with the soil pipe. Second, it disimproved apparatusassuming the parts to sion 35 and thence a portion of the same anymatter thereto. A portion of the water closed tank, which is located ata considerhollow valve body therefor is delivered of air from the bowland also discharging the comparatively small quantity of water passingto the rim aperture through pipe 42 by reason of the velocity of thejet. The effect of the jet therefore is to maintain a free passage atall times when the seat is occupiedbetwe'en the interior of the bowl andthe soil pipe and to positively withdraw not only the foul air therein,but to draw in volumes of air from the surrounding atmosphere of theroom in which the bowl is located and positively prevent any foul airpassing from the bowl to the room. As a result of this operation of thejet, the atmosphere of the room can not possibly be con-' taminated, andas before stated, the closet becomes entirely innocuous and may beemployed in any location without danger of setting up unpleasant orunsanitary conditions. As soon as the seat is relieved, the spring 27causes the front edge thereof to rise and simultaneously reseats thevalve 21 on its seat 13 and closes the water supply, thus cutting oilthe supply of water to the pipes 39 and 42 and simultaneously openingthe aperture 15 which is the main flushing aperture, thus permitting thewater accumulated in the tank 51 to pass with great force and volume tothe rim flush, this removing any contents of the bowl which may remain,thoroughly cleansing the bowl, and trap, and as the pressure and volumeof the water subsides with the gradual emptying of the tank, the lastportions of the water so admitted fills up the lower portions of thetrap and restores the water seal, thus preventing any foul .air or gasfrom passing the bowl.

In Fig. 5 I have illustrated a modification of my invention in which thevalve casing is constructed exactly in the manner shown in Figs. 1 to 4inclusive, except that the extension and the pipe connections therefromare omitted, and therefore the ventilating feature before reterred "tois not present in this modified form of the valve. This modification ofthe valve further retains the otl1er.features hereinbefore described.The parts of the valve shown in Fig. 5 are lettered to correspond withthe similar parts shown in the other figures, the letter a followingeach reference :numeral. In theop eration of this form-of the valve,when the seat is depressed, the valve is raised and the water enteringthrough the inlet aperture 12, passes around the cylindrical valve body20 through the apertures 23, therein, which in this case will have theircombined areas substantially equal to or in excess .of the area from thesoil pipe backwardly to of the aperture 12 so that all the waterentering the valve casing may pass upwardly through the hollow valvebody. The

water is prevented. Upon the seat bein released the valve descends bymeans of the spring 27* and is also assisted in closing by the pressureof water above the valve and the contents of the tank are rapidlydischarged through the aperture 15' to the rim flush, thus setting upthe siphonic action, breaking the liquid seal, discharging the contentsof the bowl, and cleansing the bowl, and restablishing the liquid seal.

In both forms of my invention it will be seen that a light. spring 27(or 27) will be sutficient to close the small inlet aperture 12 (0112)so that injurious strain upon the spud which supports the I valve casingand connects it to the bowl is avoided.
